Computing and Audio Research Laboratory
The Computing and Audio Research Laboratory (CARlab) specialises in three main research areas: "Spatial Audio", "Neuromorphic Engineering", "BioElectronics".
Our Spatial Audio research deals with all aspects of the spatial perception of sound. This includes the study of how humans localise sounds, the effect of room acoustics on sound perception, recording of spatial sound fields, playback using our 32 spherical loudspeaker array, generation of augmented and virtual reality audio, 3D voice communication systems with location aware computing, and the study of musical aspects of sound fields. Applications of this research are in music recording and playback, video games, teleconferencing, and hearing aids. At the University of Sydney we collaborate closely with the Auditory Neuroscience Laboratory and the Acoustics Research Laboratory. Taken together, our research group is probably one of the three largest research groups investigating spatial audio world wide.
Our Neuromorphic Engineering research investigates biological auditory processing and applies principles learned from biology to electronic systems. The current focus of this research is on developing a two-dimensional electronic cochlea and spiking networks that perform basic auditory computations.
Our BioElectronics research aims to develop hardware and algorithms to measure and classify biological signals, such as ECG, EMG, EEG, 3D position and location, skin conductivity, and blood oxygenation. We are researching a portable Electronic Impedance Tomography Spectroscopy device which measures tissue impedance to create an image of the tissue impedance distribution. This EITS system can be used for instance for monitoring stroke, epilepsy, and for detecting cancer.
